Demon One is a french rap singer, however he is not the most popular. His rap style is individual which is a good thing, but it takes time for some to adjust to it.His lyrics are stron and can be explicit. Some say he is almost like a French (50 cent) if you like. His backround music is not exactly the usual hip-hop beat like lil` Wayne and Akon have.. It`s quiter and has less beat.Some people say it sounds a little jazzy. Demon One:original name :Hakim Sid born in Algeria.
